15 Street Tire Racing Tips
By Don Terrill (c)2005
No matter where you live in this country, you're not more than two hours from a race track, and thus there is no excuse for hot-rodding your car on the street. So, I will only be talking about racing your street car at the track.
The biggest problem I see for street tired cars is traction. Here are some tips:
- More weight in the trunk - More weight on rear tires.
- Less weight on front of car - Allows for more weight transfer.
- Less converter speed or launch rpm - Less shock to the tires.
- Less first gear ratio in trans - Less torque multiplication.
- Less rear gear ratio - Less torque multiplication.
- More camshaft duration - Kills low end torque.
- Tighter lash - Kills low end torque.
- Less ignition timing during launch - Kills power.
- More fuel during launch (Squirters?) - Kills power.
- Wider tires - Better traction.
- Taller tires - Better traction.
- Softer tire compound - Better traction.
- Tire pressure tuning - Better traction.
- Tuned front suspension - Allows controlled weight transfer.
- Tuned rear suspension - Keeps rear tires planted.
